To be honest with you 1000 euro seems to be a good price, i have been checking prices for a spiral staircase for the last 6 mths [external one] as i need one to join 2 roof terraces, you can try your local blacksmith for a quote or there are plenty of scrap yards between cambrils& reus.. i forget the name of the road but it goes under the ap7 towards reus....be lucky.
